Capacitive vs. Resistive Touch Panel - What feels better?

24 Feb.,2023


The company has a group of cooperation teams engaged in the Multi-touch PCAP Touch Screen, Capacitive Touch Screen industry for many years, with dedication, innovation spirit and service awareness, and has established a sound quality control and management system to ensure product quality.

The history of user interface devices is a pretty interesting one. And, while looking at how different machines have interacted with humans throughout the years, one may think it is a funny one also. From punched cards to joysticks and gloves. From joysticks and gloves to mice. From mice to voice, ingenious engineers have developed different ways in which the user will talk to the machine. Today, however, we are going to talk about only one way, the Touch Panel.

Our Easy Development boards can come with an Easy TFT Touch Panel. These TFT touch panels were all resistive. The mikromedia boards all featured the same TFT resistive touch panel also...until now. With the release of the new mikromedia HMI boards, we have introduced capacitive touch screens to our line of product. But, that doesn't mean anything if you don't know what you are looking for in your touch panel, right? So let's see what the distinguishing factors are between the capacitive and the resistive touch panels.

Resistive touch panel

Resistive touch screen technology

The resistive touch panel is the one with which you have to use a little bit of muscle to get it going, as they work by applying actual pressure to the screen.
The technology behind the resistive touch panel is pretty straight forward:
The panel is made out of a glass screen and a film screen, which are separated by a little gap. Inside the gap, on each screen, there's a film layer which contains electrodes. When the film screen is touched with a finger or any other type of object, it bends. When bending, the two electrode films connect, which generates a current flow.

Pros : 

  • Since the display works by applying pressure, you can use it with any surface you can imagine: a stylus pen, a regular pen, wearing gloves etc. The operation doesn't change based on the material used
  • The position of the touch is pretty accurate, which makes it good for handwriting recognition and similar usages.
  • Resistive touch panels are cleaner: since users most likely use stylus pen or other robust semi-sharp objects, there are less germs and skin grease on the touch panel.


  • Like said before, the screen senses pressure, this may be a bit frustrating, since not every touch is going to be recognized, only the ones with enough pressure applied
  • Lower display quality: since light has to travel through two film layers, the light transmission is lower, which results in lower display quality
  • Resistive displays tend get worn out faster, and have lower shock resistance
  • No possibility of multi-touch recognition, unless you want to re-engineer the way they work.

Capacitive touch panel

Capacitive touch panels don't require as much pressure as resistive ones, but they do need you to be conductive!
There are two different versions of capacitive touch panels: surface capacitive and projected capacitive. Both of them work by detecting a change of capacitance on the screen.

Surface capacitive

The surface capacitive is a simple one: there's a thin layer of electrodes which lies under a glass surface covered with a protective layer. Four electrodes on the corner of the panel are providing electric voltage to the film. When a conductive material (such as a human finger) is near the electrode film, there's a change of the electrostatic capacity. Measuring these changes, the controller figures out where a touch has occurred.

The surface capacitive is often used on big surfaces, since the touch sensing isn't really accurate.

Surface capacitive display

Projected capacitive

This one is a little more complex. Underneath the glass and protective cover lies a pattern of electrode layers. This pattern forms an X,Y plane which the controller uses to calculate a touch event. Forming the pattern results in more accurate touch sensing, which is why this type of touch panels are used on mobile phones and similar small devices.

Projected capacitive display


  • No force required: the capacitive touch panel will react as soon as you place your finger to as near as a couple of milimeter near the screen.
  • Accurate touch recognition, especially with the projected capacitive screen
  • Good display quality: no matter if inside or on the sun, the display quality is usually better than that of a resistive screen
  • Possible to implement multi-touch.


  • Touch sening doesn't work with all materials: gloves, for example, aren't conductive, so you must always press the screen with something conductive in order to establish contact. There are many workarounds for this, but it surely represents a problem.
  • Price: capacitive screens are usually a little bit more expensive than resistive ones
  • Hygiene: since a full finger connection is needed, usually these types of screens are more stained and germ filled than capacitive ones


There you have it! Want to take out your frustrations on a touch display? Why not resistive?? Want to graciously type away like a piano maestro, capacitive is the display for you. Fortunately, we now support them all, so you can choose whichever interface suits you the most!
